1. Another feature of electronic transitions is that the selection rule for pure vibrational transitions no longer applies. 2. However, even in a regularly Octahedral complex there are ways of weakening the effectiveness of the Laporte selection rule. 3. In some cases overall selection rules leave little doubt. 4. It is less stringent than the spin selection rule, partly because the mechanisms for getting round it are more effective. 5. The selection rules depend on the symmetry properties of the electronic transition. 6. This rule is known as the Laporte selection rule. 7. Those with are formally forbidden under the fundamental vibrational selection rule. 8. Delegate selection rules in Rhode Island and Connecticut are more favorable toward McCain, who can submit a slate he desires in those states. 9.
